GEORGE W. BALDWIN, OF SCHAGHTIOOKE, NEW YORK, ASSIGNOR OF ONE- HALF TO GEORGE H. STEVENSON, OF SAME PLACE.

PEN-HOLDER.

SPECIFICATION forming part of Letters Patent No. 404,027, dated May 28, 1889.

Application filed June 19, 1888. Serial No. 277,667. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. BALDWIN, a citizen of the United States, residing at Schaghticoke, in the county of Rensselaer and State of New York, have invented new and useful Improvements in Pen Holders, of which the following is a specification.

My invention relates to pen-holders, primarily, and has for its object to furnish a .pen-holder which by a simple and inexpensive mechanism connected therewith may be made to accommodate either a large or small pen, or may be readily made into a fountainpen by substituting a fountain for the small pen.

With these objects in view my invention consists in the improved construction, arrangement,and combination of parts hereinafter fully described, and afterward specifically pointed out in the claims.

In the drawings, Figure l is a perspective view of a pen-holder constructed with my improvement, a portion of the outer tube being removed to clearly show the interior construction. Fig. 2 is a similar view, a large pen being inserted and properly secured therein. Fig. 3 is a similar view with a small pen inserted and secured. Fig. 4 is a smaller View with a large pen and fountain inserted and secured, and Figs. 5 and 6 are detailed views showing modifications of the cam or eccentric clamping or securing mechanism.

Like letters of reference mark the same parts in all the figures.

Referring to the drawings, A is the pen stafi or handle, upon the end of which is fitted a tube, B, as is ordinarily the case. \Vithin this tube are located the various parts of the mechanism which forms my improvement.

0 and D are two partial sections of cylinders or curved plates bent on curves of less radii than that of the tube B, the radius of the curved plate D being also slightly less than that of the plate 0. These plates are loosely secured within the tube B by means of a pin, E, passing through slots in said plates. The

tube B is provided with a slot, b, in which works a cam or eccentric, F, pivoted on apin, G, secured in the sides of the tubes. When the curved plates 0 and D are in place in the tube, as described, spaces H and I are provided, the former between the tube and the plate and the latter between the plates 0 and D, the former being on a larger curve than the latter. Into the space H a large pen may be placed, and into the space I a small pen, either of which may be securely clamped by the manipulation of the cam or eccentric F in the well-known manner by turning down upon the inner plate, D. This turning may be effected by the lever f or by the milled surface shown in Fig. 5.

The eccentric maybe made to operate with a spring-pressure by the means shown in Fig. 5, It being a spring secured to its contactsurface.

In order to form a fountain-pen, the fountain J may be used in connection with the large pen5,;a s shown in Fig. 4.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A pen-holder provided with a curved plate loosely secured within the tube, and a cam,wher eby a pen may be clamped between the curved plate and the tube by means of the cam, as set forth.

2. A pen-holder provided with two curved plates loosely secured within the tube, and a cam, said plates being of different curves, as set forth.

3. A pen-holder provided with two curved slotted plates, a pin passing through the slots and secured to the tube, and a cam-clamp operating to secure a pen in the holder, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. BALDWIN.
